4 - compatible: Should be "atmel,sama5d2-i2s".
5 - reg: Should be the physical base address of the controller and the
6 length of memory mapped region.
7 - interrupts: Should contain the interrupt for the controller.
8 - dmas: Should be one per channel name listed in the dma-names property,
9 as described in atmel-dma.txt and dma.txt files.
10 - dma-names: Two dmas have to be defined, "tx" and "rx".
11 This IP also supports one shared channel for both rx and tx;
12 if this mode is used, one "rx-tx" name must be used.
13 - clocks: Must contain an entry for each entry in clock-names.
14 Please refer to clock-bindings.txt.
15 - clock-names: Should be one of each entry matching the clocks phandles list:
16 - "pclk" (peripheral clock) Required.
17 - "gclk" (generated clock) Optional (1).
18 - "muxclk" (I2S mux clock) Optional (1).
21 - pinctrl-0: Should specify pin control groups used for this controller.
22 - princtrl-names: Should contain only one value - "default".
25 (1) : Only the peripheral clock is required. The generated clock and the I2S
26 mux clock are optional and should only be set together, when Master Mode
